Abstract:

"You have two options when you walk into a room," says public speaking expert Richard Levick about the art of giving speeches. Most entrepreneurs find speech making to be either terrifying or a waste of time. Too many CEOs see dealing with the media or making presentations as an interruption, but it's as essential to doing business as customers. If you can't deliver energetic and commanding speeches, or polished and articulate interviews, then you're short-circuiting your company's future. It's time to do something about it.
